filesize file size calculate


Versions (?)

Calculate and return filesize of file in different units of measurement

 / Published in: PHP
 

URL: http://skyward.nefec.org

Simply pass the path to the file, the desired units of measurement, decimal rounding, and separator. For example, a 1024kb file (1mb)

$filesizeStats = getFilesize("path/to/file.jpg", "kb", 2, " ");
print_r($filesizeStats);

//will return

array (
        "rawBytes" => 131072,
        "convertedSize" => 1024.00,
        "convertedSize_formatted" => "1,024.00",
        "units" => "kb",
        "formatted" => "1,024.00 kb"
    )
